The developer never "officially" announced it was launching "Titan," though over the last seven years it didn't hold back from discussing the big project in development, and the hope of taking the MMO model to the next level.

"After completing our re-evaluation, we determined that 'Titan' just wasn't the game we wanted to make. We've always been about working on the things we're the most passionate about, and not just doing what was expected," an Activision spokesperson said.

"We've come to this decision with projects in the past, and it has always resulted in us being able to deliver better games for our players."

Activision's "World of Warcraft," the biggest and most successful MMO game of all time, pushed the company to try to develop a second game of this type.

The previous game's success more than likely prompted the game maker to reconsider and focus on making sure its next game—whether it's an MMO or something else—lives up to the standards and expectations that "World of Warcraft" set.
